Ward which retains the detent arm in the to the slightest extent the pinwill be released and the spring will act to tilt the lever, the, I pinmoving upward in hole 21 and the right arm of the lever swingingdownward and releasing the detent arm, which causes the operatingmechanism to ring the bell. 'I he ball when it settles back to placewill roll against the pin but cannot move the pin downward the ball willbe stopped against one side of the pin, so that the ringing of the bellwill continue until the operating mechanism if controlled .by a springhas run down, or if electric ringing mechanism is used, so long as thebattery holds out unless it is stopped by the operation of the look. Aperson knowing the combination can stop the ringing of the bell bysetting up the combination and mov"" ingthe locking bolt to theunlocking position; that is, toward the left from the position Themovement of the looking bolt to the unlocking position swir igs thestopping lever and moves the lower end of said lever, which is now inengagement with lever 16, downward, swinging the right end of lever 16upward which raises the detent 'lhe oscillation of lever 16 moves pin 20downward to the position shown in ig. 1 against the .power of the springand permits the ball to 'roll to its normal position on top of and inengagement with the end of the pin, as in the drawing, andretains theparts in this osi tion against the power of the spring unti the ball isagain displaced.

Having thus described my invention, I

1. An alarm of the character described comprising bell mechanism having"a detent arm, a pan having a dish-shaped bottom with a central hole, aball in said pan, a lever one arm of which engages the detent arm theother arm being provided with a pin project ing through the hole in saidpan to be engaged by the ball to lock the bell mechanism out ofoperation, and me ans for tilting the lever and releasing the bellmechanism when the ball is displaced from the end of the pin, the pinbeing of a length to form a stop to prevent the ball from rolling backover it when said pin is'raised. Y

2. An alarm of the character described comprising hell mechanism havinga detent arm, a pan having a dish-shaped bottom with a central hole, aball in said pan,- a lever one arm of which engages the detent arm theother arm being provided with a pin projecti.

ing through the hole in said pan to be eni gaged by the ball to lock thehell mechanism 1 out of operation, and a springbearing upon 1 one arm ofthe lever to tilt said lever and release the bell mechanism when theball is displaced from the end of the pin, the pin being of a length toform a stop to prevent the b from rolling back over it when said pin israised.

3. An alarm of the character described comprising bell mechanism havinga detent arm, a pan having a dish-shaped bottom with a central hole, aball in said pan, a lever one arm of which engages the detent arm theother arm being provided with a pin projecting through the hole in saidpan to be engaged by the ball to lock the bell mechanism out ofoperation, means for tilting the lever and releasing the bell mechanismwhen the ball is displaced from the end of the pin, the a pin being of'a length to form a stop to prevent the ball from rolling back over itwhen said pin'is raised, and means for returning the lever to itsnormalposition against'the power of the spring and permitting the ball toagain engage the end of the pin.

' 1. An alarm of the character described comprising bell mechanismhaving a detent arm, a pan having a dish-shaped bottom with a centralhole, a ball in said an, alever one arm of which engages the ctent armthe other arm being provided with a pin projecting througlf the hole insaid pan to be engaged by the ball to lockthc bell mechanism out ofoperation, means for tilting the lever and releasing the bell mechanismwhen the ball is displaced from the end of the pin, a stopping lever forreturning the lever to its normal position,*a locking bolt and acohnection betwcenthe locking boltand the stopping lever.

.5. .in alarm of 'the character described comprising bell mechanismhaving a detentarm, a pan having a dish-shaped bottom with a centralhole, a ball in said pan, a lever one arm of which engages the detentannand the i other arm being provided with a pin pro ecting tln'ough thehole in said pan to be engaged by the ball to lock the bell mechanismout of operation, means for tilting thevlcver and releasing thebcllmechanism when the ball is displaced from the end of the pin, the pinbeing of a length to form a stop to revent the ball from rolling backover it w en said pin is raised, a stopping lever one end of which isada ted to engage the lever, for the purpose set mm, a locking boltan'dan arm pivoted to the locking bolt and connected to the stoppinglever.
